Costumized plugin for Ultimaker Cura 4.4.0

Dear Sirs.:

I’m traying to make a plugin for my Ultimaker Cura 4.4.0 and I put it according to this instructions:

Installation:

  1. Go to the “scripts” folder and open “DisplayRemainingTimeOnLCD.py”
  2. In the top-right corner is a RAW button, right click it and choose “Save link as”
  3. Save the file to your Cura plugins folder. The path should look something like: “C:\Program Files\Ultimaker Cura 4.2\plugins\PostProcessingPlugin\scripts”.
  4. Now open Cura and verify the installation worked. This is done by opening “Extensions” -> “Post Processing” -> “Modify G-Code” -> “Add a script” -> “Display Remaining Time on LCD” and then selecting “Enable”.

But Cura stayed as before, the new script doesn’t appears. What could be the problem?

Thanks and best regards.
